JUSTIN T. HURLEY, OF NEW YORK., N. Y.

MULTIPROCESS RIEGISTER.

Application filed October 30, 1923. Serial-No. 671,754.

To allfwhom t may concern I -Be it known that I, JUSTIN T. HURLEY, a citizen of the United States oi America, and residing at New York, in the county1 of New York and State of New York, have invented new and useful Improvements in VMultiprocess -Re isters, of vwhich the following is a speci cation. My invention relates to machines for direct acting computation in the -our mathe hiatical processes in 'conjunction with registering and listing features. The machine herein lillustrated andl described and embodying my invention comprises a. key-board having the key columns arranged in the usual manner, the kevs of which may be de- 'pressed simultaneous y in theseveral orders -and'each column of keys is flexible with respect to adjacent keys of the column. It is arranged that the key-controlled differential mechanism may operate conjoint-ly with lthe listing'or printing mechanism, or may beconveniently isolated therefrom, and also that the listing devices may be operated withoutV influencing the totalizer wheels which are arranved in a transversely'movablecal'riage. 'he machinealso comprises a series of multiplicand dials, disposed at the foot-.of the key columns, which indicate the sum set up on the board. The machine also comprises a series of dials arranged adjacent to and aligned with the multiplicand dials and known as the multiplier, andadapted to show the multiplier u in multilication and the quotient in division. he 4machine' being direct acting there is-rcquired but. one setting. up of the multiplicand for mliltiplying and one setting up of the divisor in dividing operations, the results of such processes being readA at a glance from the three sets of dials, that is to say, from the multiplicand, the multi-v plier. and the totalizer. For addition and multiplication the totalizer wheels turn toward the operator, While for subtraction and division .they tur-n from the operator;

thereforel the necessity` for mentally assistmg the machine'bylaboriously compiling i complements for each sum is obviated. lvThe vmac 4which cooperate with the differentials fory ine furthermore com rises devices th reception and registering of cash, v rece ed ron account, paid-out and. charge transactionsmnd will print the designating symbolpof the different transactions together with the amount involved, while forv obtainq ingV a total or sub-total of such listed 'sums the kmachine may if desirable be operated rapidly in a key-driven manner.

Arranged on the cross-rod 30, alongside thepla-tes 29, is a vseries Aof actuators or Sectors 37, each of which is connected to a plate-29`, by a spring 28 and' 'normally rests differentials may be operated atn will' and released by key 23 without infiuencing the totalizer.

Loose upon the 'shaft 28 is the main operating lever 45, to which is secured a Wing 46, havino` a ,wiper extension 47 the func,-

fff'tion of w ich is hereinatter described. Iii 'slot and pin connection with the wing 46 is' a link 48, whose other end is pivoted to the rock shaft 42'. When lever 45 is pulled toward the operator 'and just before attaining full displacement, it will move the link 48, andswing the frame as shown in Fig.. 13, whereby-the fingers 43 will be displaced to release the sectors 37. If when such re# lease is madekthedifi'erentials are at nor-mal there will be no movement of the sectors. If however', any of the keys are set the sectors for `such displaced differentials will be instantly drawn against the stud 39 by action of spring 38. .An extra finger 43 located near tlie left side of the machine, Y Figs. 2 and 9, is secured to the shaft 42 and 'sectors are .released rests normally against a fixed stop 49. Against a stop the frame piece 40 is .normally held by a Icompression spring 5l.

Near the right-handv sideof the machine, Figs. 1 and 4, is located a swinging key 52 which is -pivot'ed, as shown, in thc machine frame.` This key 52 which isknowii as a non-print. or add-repeat key carries the symbol N und is restored by a'coiiiprcssion spring 53. The key 52 rests against a .stud

' 54 fixed in a wing 55 which is pivoted 'in the machine frame.

The wing 55 is connected by a link 56 .with a bell-crank 57, pivoted on the rod 30 and having one vterminal resting normally against a stud 58 that extends fromtlie side of link 48. It will be vseen that if key 52 is struck itwill move link 48- to displacev the fingers 43' and release the sectors 37, thus dispensing with `the .ervice of lever 45 inperformingtliis function. Willen it is desired to enter a sum or sums on the totalizer without listing such su'iiis the main 'lever 45 is not operated. Instead the i keys 52 and 23 are utilized. First the differentials are set to the amount desired and the keys. latched by) detents'15; next the y operationfqf key 52,

then the keys Should be released by pulling the error key or lever 23 toward the oper ator.` In this manner sums may also bededucted from the totalizer without operating the printing devices, but the wheels should'first be set for subtraction by de#A vices hereinafter described. From the above example it will vbe seen that if keyl 152v Y is held depressed by a simple catch that is not shown herein, and the error key pulled toward the operator and left in this displaced position the keys operated will-not latch, and the sectors being free, will'i'riove in both directions along with the ilates'."v A 89 29. In this manner a' rapid keyriven structure with direct action totalizer for the four mathematical processesJ Without the use of complements, may be evolved. liesul'ts obtained loperating a machineby theA key-driven jmethod, being sometimes er" comparable with the key-setmodc'of operation described/herein.

The error key 23, which as observed .in l

Fig. 4, normally stands vertically, 'is

adapted to be sot in `either of two operating y positions, orin other words has two functions. lVlien pulledh'toward the operator the detent plates 1,5 are operated, as explained,

to release the keys. When the key is uslied rearwardly as far as it will g'o the ar 18 is moved forwardly a distance determined' by the length ofthe-slot in tlie'link 59 lthatconnects the key to the bar. Movement of key 23 to the rear readjusts' certain parts to A clear the sectors and render thelever 45 iiieffective for releasing .the keys, an arrangcnient required particularly when the nia'- cliine is to be used for repeating on both the listing stri and the totalizer an amount set on the key- )'oard. Pivoted to the framework near the right-hand side of the macliiue is a tappct .60, which pivotally supports one end of a horizontal link 61, F igs. 2 and 4, the. free end of which is normally adjacent to 'one end of the link 48. The other end of link G1 is pivoted to 'a downwardly extending portion of the right-hand ariii 19 of' the key release bar `18,-as shown Amore distinctly in Fig. 7. A pivoted, spring pressed arm 62, resting, against a stud 63 in the side of link 6i and stopped in one direction ,by= a fixed stud (S4, holds the bar 1S in iioririal position adjacent to, oi.' in actual contact with thel detcnts 15 without exerting pressure thei'on; l when lever 45 is pulled .forward toward the operator rthe wiper 47 wipes over the.

The dials 65, known as the multiplieand and adapted to indicate at all times the positions of' the differential mechanisms are piroted on a cross-rod (36,. Fig's- 5 and 8, fixed in theframe-work` and are each provided` with a pinion 67, which is constantly meshed with a sector G8, Figs. 2, 5, 7 and 10, that is integral with the bell-crank 32.

Ribbon reels 122 and 123 are pirotallyv supported b v the bar121` as shown in Figs. 4

and 5. Referring to Figs. 1 and 5. it will be observed that the-pressure bar 108 carries twor rearwardly projectingmembers 124-,

which are provided with slots through vwliichpasses the ribbon 125 from reel to reel' contact with the arm 104` at ,which time the across the face of the type-bars.A

- The'determinator arms 104 are adapted Iupon key action, to be swung radiali)v npward from normal and set. in either of nine possible positions as determined by (he posi'- tion of `plate 29, and when so set. the operating lever 45 will he pulled to lift the rod 117, whose range of sweep is somewhat greater. than the arm 104 in its ninth position. .'I`he type-bars 99, impelled by spring' 119,. will nieve upwardly until stopped by appropriate type figure will be at the printing point.

colel the arm 115 acquires an elevation sufficient to displace upwardly the link 114. When so displaced, the-link` 114 will operate the toggle, shift Vthe bar 108 to the rear and force t-he type-bars against the platen wit considerable pressure. The forward .movement of lever 45 having displaced the `fingers '43, the sectors whose, differentials have beenset will have fallen againstthe studs 39.

It should be'explained.here-that in additive cursion of the sectors while in subtractive'processes it is operated on the first. half of the sectors excursion.

Referring now to Figs. 1, 2,7 and 9, it is,

.seen that a spring-retracted differential bar 126, loose on the shaft 20is connected by-a short .link 127 to a wing 128, which is loose on the rod 30.

ing known as a communicating wheel fromI the fact that it communicates to its digit wheel both driving and transfer motion. llach digit wheel is provided'with a length'- enedhub forming a sleeve 181, to which is ixed an eccentric 182 arranged axially withi an externally toothed gear plate 183, Fig.

19,`appropriate to the higher orderl wheel and which operates its associated pin-gear wheel 179. Transfer connection from each 4digit'wheel to the next higher set is thus established. A' stud 184 secured to the face of plate'v183, reciprocates in a slot 185 provided in a drivin arm 186, which is fixed to a ratchet whee v187'tl1at rotates' on the sleeve181. The ratio of teeth on gear 188 sie to vthe teeth or pins 180 on wheel 179 .as 9:10 which iinplies` that a complete revelution of eccentric 182, while the arm 186 remains stationary, will cause the gear 183 to rotate vthe wheel 179 through thirty-six degrees, the stud 184 meanwhile reciprocating in the slot. 185.- Regardless of the poi' sition of eccentric 182 the ratchet 187-` when driven by the operations of'sector 37, will in 'a like degree rotate the gearp1ate 183 and thereby the wheel 179, whose motion will be communicated through digit wheel 177, veccentric 182 and gear. 183 to wheel 179` of higher order. Thistransfer moreinent to wheel 179 will be continuous with movement of thelower order digit wheel.

Obviously if wheels' 177 were integral with wheels 179 this continuous transfer feed, simultaneously. with driving actuation'v ol ratchet 187, next lower in the order, would carry one digit out of view from the read-4 ing point, and the indication would be blank until upon 'additional actuation of said ratchet 187 another digit was'caused to appear. A n important feature of my improvements is the provision of means lforI aligning and holding the appropriate digit in view at the reading point until wheel 179, having progressed one-tenth in either direction, eon'nnimicatesits 'position to its associated digit wheel, resulting in immediate appearance at the reading point of the digit corresponding to the position attained.

Referring 'particularly to Fig. 20 which illustrates the higher order side of the digit an arcuate slot\189, provided in the web` of the digit wheel. vWith the parts at nor,-

mal and wheel 177 standing at O, the stud 188 will be located near the lefthand end of slot' 189. Arms 190 and 191a-re piv'otedy 181 and are normally drawn toward each other at their free ends by springs 192 and to the digit-wheel web. one exteiiding t'o the left and the other to the right. of the sleeve 193 that have a common anchorage point on.

the kdigit-.wheel web. Fixed to a rod 194 which is secured in the carriage end-plates and extends beneath the digit-wheel series,

`are brackets 195, one appropriate to each digit-wheel,and toV each of said brackets is secured a ratchet disk 11964that .encoml passes the sleeve 181. vTothe arm 190 near its Vfree end, is pivoted a pawl 197, and similarly the arm 191 carries a pawl 198, both of said pawls being spring-pressed as -shown,

against the ratchet 196. f Integral withth arm 191 is an extension 199 which when the wheel stands at 0, is in Icon'tact with afstnd I 200 that extends from the wheel 179 through the arcuate s lot 201, formed-in thedigitwheel web. An extension similar to the i is'to be engaged at times by the stud 1.88. Pawls 197 and 198 are each' provided with' a pin 202 which extends -across the and 191, and will there ore be moved clear of said ratchet 196 when the arm is fully displaced. vAt other times when the arm is at normal, the pawl is adapted to swing radially on its -pivotal point when drawn' back overthe-rhtchet teeth. In the absence member 199 is 'supplied tothe arm 190 and Aim' 'outer edge of their 'su porting arms 190 of driving or transfer movement to operate wheel 179 the digit `wheel willl remain'A locked against movement in either direction',

by 'said pawls 197 andl .198. In Fig. 20 the position of parts show that the arm 191 has been displaced by the stud 200 to disengagc the paw] 198froin the ratchet 196, which will allow the spring 193 to turn the wheel 177 in counter-cloclm'ise or subtractive direction., Should the stud 200 in this instance, be actuated by transfer only, the pawl 198 will' engage the next tooth of ytheratc'het 196 and stop the digit wheel. The teeth of ratch-v 'et 196 when engaged by pawl 198 prevents pawl 197 frein the ratchet teeth, permitting f ythe now extended spring 192 to [lick the wheel around. Should the displacement of arm 190 be caused by transfer movement only, the pawl 197 will engage-the next tooth of the ratchet. lVhen such displacement is fcaused by transfer action,..plus the drive imparted by depression of key one, the pawl 197 will engage the second tooth of the '1'30 ratchet.v
